I replaced the hammers, shanks & flanges with, respectively, Abel Hammers, & WNG carbon fiber, rebushed the keys and regulated a nearly 30 year old Yamaha C5 in a Public high school last summer. When I completed the job in the 3rd week of August, I tuned it. It took 2 passes to tune it DOWN to pitch we had a cool dry summer(only 3 days above 90). This of course was a terrible summer for pianos, although we had less rain, the humidity was still high all spring/summer/fall but the AC in most places ran less, some days hardly at all. By mid summer I had developed a method with my Cyber Tuner for a faster 2 pass tuning by setting my first pass at A-438 and the 2nd at A-440. But I digress. I was called last week to tune the afore mentioned C5, while I was there one of the vocal instructors asked if the "new hammers" might have caused it to go out of tune so fast? I asked her when it was last tuned and who had done it, she said I was. I said you mean it hasn't been done since August, she said yes. I told her I was amazed they hadn't called before now, the only explanation I could think of why it hadn't gone flat with the onset of heating season(we just celebrated our first day above 40 degrees in 90 with only 6 of those above freezing, a deep snow pack and many nights at or below zero)is that the school has a large swimming pool inside. The bass was 10 to 15c flat the tenor 20 to 25c flat and the treble 10 to 15c sharp. I explained all of that to her and that it should have been tuned after the heat came on, she seemed to accept it.
